This will make you feel warm and fuzzy. Brazilian footwear maker Melissa teamed up with 3M to create an wonderful exhibition at the opening of their São Paulo flagship store – Galeria Melissa. They took an amazing 350,000 colored Post-its, 30,000 of which had spontaneous messages of love written on them from the local community. The end result is heart-warming time-lapse video which itself took 5 months to finish.
